WALTER BUSZEK AND THEOPI-IILE SOKOLOWSKI, OF ST. LOUIS, MISSOURI.

WATCH.

To all whom t may concern.'

Be it known that we, TAI/rmt BUSZEK, a subject of the Emperor of Austria-Hungary, and THEOPHILE- SoKoLowsKr, a subject of the Czar of Russia, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in lVatches; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in watches.

One object of the invention is to provide a watch having arranged therein two inde` pendent operating sets of works either of which may be removed without disturbing the other whereby if either set of works requires repairing or cleaning the same may be removed and left with the jeweler, while the watch may be carried and used with the remaining set of works.

Another object is to provide an improved means for throwing the individual winding mechanism of either of the sets of works into and out of engagement with the main winding mechanism operated by the stem of the watch. v

lVith these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.`

In the accompanying drawings: Figure 1 is a plan View of the face side of a watch constructed in accordance with the invention; Fig. 2 is a similar view of the watch works with the face of the watch removed; Fig. 3 is a plan view of the rear side of the works; Fig. 4 is a similar View with the balance wheels and rear plate of the main set of works removed; Fig. 5 is a plan view of the rear plate of the main set of works; Fig. 6 is a plan view of the supplemental set of works removed from the casing; Fig. 7 is a side or edge view of the same; Fig. 8 is an enlarged plan View of a portion of the works showing more clearly the means for connecting the main winding and setting' mechanism with the individual winding mechanism of the main or supplemental sets of works; Fig. 9 is a similar View with the gear support-ing and shifting plate removed and showing the stem winding mechanism in its normal position or the Specification of Letters Patent.

position the same occupies when the winding stem is pushed in and the parts arranged for winding the main springs of the works; Fig. 10 is a View similar to Fig. 9 showing the parts of the stem winding mechanism shifted to a position for setting the hands of the main set of works; Fig. 11 is an enlarged cross sectional view through the stem winding and setting mechanism taken on the line 11-11 of Fig. 8; Fig. 12 is a side view partly in section of the gear shifting plate and gears for connecting the stem winding mechanism with the winding gears of the main and supplemental works; Fig. 13 is a cross sectional View through the stem winding and setting mechanism taken on the line 13-,13 of Fig. 9.

Referring more particularly to the drawings, 1 denotes the face or dial plate of our improved watch, said plate having thereon the usual dial numbers 2, with which the hands of the main set of works coperate and a dial 3 with which the hands of the supplemental set of works coperate. The dial plate 1 is secured in any suitable manner to the front gear supporting plates t and la of the watch said plates having on their outer side an annular spacing and supporting ring 5 which forms a space between the inner side of the dial plate 1 and the outer side of the gear plates 4 and 4a in which are arranged the gears which connect the main winding mechanism with the separate or individual winding mechanism of the main and supplemental sets of works. Spaced from and secured to the inner side of the gear supporting plate l is the rear gear supporting plate 6 for the main set of works, and adjacent to the inner side of the rear gear supporting plate 6 and spaced a suitable distance from the inner side of the front gear supporting plate 4a is the rear supporting plate 7 for the supplemental set of works. The plate 7 is of segmental shape and has its inner edge notched out to provide space for the gears of the stem winding mechanism said plate 7 being secured to the inner side of the frontgear supporting plate ta by fastening means entirely separate or independent from the fastening means of the rear plate 6 of the main set of gears, thus permitting said main plate to beremoved together with the main set of works without in any manner disturbing the plate 7 or the supplemental set of Works supported thereby. In like manner main set of works is connected to a winding shaft 12 one end of which projects through the rear gear supporting plate 6 and is squared to receive a key whereby said spring may be wound. On the opposite end of the shaft 12 and engaging the front gear plate 4 is a spring winding gear 13 which is adapted to be engaged by a pinion forming part of a stem winding mechanism hereinafter described whereby said spring of the main set of works may also be stem wound.

The supplemental set of works which, as hereinbefore stated, is arranged between the front gear plate 4a and the rear gear supporting plate 7 and comprises a main spring 14 which is connected by a train of gears 15 to the arbors of the minute and hour hands 16 and 17 of the supplemental set of works. The inner end of the main spring 14 of the supplemental set of works is connected to a winding shaft 18 one end of which projects through the segmental supporting plate 7 of the supplemental works and through the plate 6 of the main works. The projecting end of the shaft is squared and is adapted to receive a key whereby the spring 14 may be wound. The opposite end of the shaft 18 projects through the front gear plate 4ZL and has fiXedly mounted thereon a spring winding gear 19 with which is adapted to be engaged a pinion forming part of the main stem winding mechanism hereinbefore referred to and which will be hereinafter described. The gears 13 and 19 of the main springs for the two sets of Works are provided respectively with spring projected pawls 2O and 21 whereby said gears are held against retrograde movement and the springs from unwinding.

The main stem winding mechanism comprises a sleeve or socket 22 which is revolubly mounted in a bearing lug 23 to the inner side of the front gear plate 4, said sleeve having loosely mounted on its inner end a spur gear 24 on the inner face of which is formed a series of clutch teeth 25 forming one member of a clutch hereinafter described. The sleeve or socket 22 is provided with a square bore with which is slidably engaged a short rectangular gear supporting and clutch operating shaft 26 which is adapted to be projected or forced inwardly by the stem 27 of the watch-whereby the inner end of said shaft is brought into engagement with a spring clutch shifting mechanism (not shown) but which may be of the usual or any suitable construction and which is engaged with a combined clutch member 28 and crown gear 29 which is slidably mounted on the shaft 26 and is turned thereby. The crown gear 29 is adapted to engage an idle pinion 30 mounted on a stub shaft on the plate 4 and which is connected by the usual pinions to the arbors of the minute and hour hands 10 and 11 of the main set of works whereby A said hands may be set.

Zhen the stem 27 is in its normal position in the sleeve or socket 22, said stem will force the shaft 26 inwardly thus causing said shaft to actuate the clutch shifting mechanism whereby the combined clutch member 28 and crown gear 29 are shifted to bring said clutch member into engagement with the clutch teeth 25 on the gear 24 and to disconnect the crown gear 29 from the pinion 30, as shown in Fig. 9 of the drawings. lVhen the parts are in this position the main springs of either of the sets of works may be wound by said stem through the arrangement of the gears hereinafter described. lhen the stem 27 of the watch is pulled out to its retracted position and the pressure thereof removed from the shaft 26, the clutch shifting mechanism will operate to throw the combined clutch member 28 and crown gear 29 out of engagement with the clutch teeth and into enga-gement with the pinion 3() thereby connecting said stem with the setting gear for the hands of the main set of works, asshown in Fig. 10 of the drawings. Arranged on the plate 4 in line with'and adjacent to the stem winding mechanism is a gear supporting and shifting plate 31, said plate being pivotally mounted on a combined bearing and fastening plate 32 on the inner side of which is formed an annular bearing boss 33 which extends through a circular opening in the shifting plate 31 and, which engages the outer side of the plate 4 to which said plate 32 is secured by screws 34 as shown. The plate 31 is provided with an annular flange 35 which fits into an annular recess 36 formed in the outer side of the plate 31 whereby the outer surfaces of said plates 31 and 32 are flush. The inner end of the boss 32 also forms a bearing for agear ring 37 which is revolubly mounted on said boss between the inner side of the plate 31 and the outer side of the plate 4 as shown. The gear ring 37 when thus arranged is in operative engagement with the spur gear 24 on the sleeve or socket 22 of the stem winding mechanism whereby said gear ring is revolved.

Arranged in the opposite ends of the shifting plate 31 and projecting beyond the into engagement with the spring winding gear 13 of the main set of works or the spring winding gear 19 of the suppleinent-al set of works whereby either of said springs may be wound by the stem Winding mechanism hereinbefore described. The shifting plate 31 is turned and the idle gear 40 held in operative engagement with the spring winding gear 13 of the main set of works by a flat spring 42 whereby the stem winding mechanism is normally held in position for winding the spring of the main set of works, as shown in Fig. S of the drawings. In order to shift the plate 31 to disconnect the gear 40 from the spring winding gear 13 and to bring the gear 41 on the opposite end of said plate into engagement with the winding gear 19 of the spring for the supplemental set of gears, we provide a bell crank plate shifting lever 48 the inner end of which is adapted to engage a notch 44 in the adjacent portion of the shifting plate 81. The opposite end of the bell crank lever 43 is provided with a curved linger 45 which projects through a notch 46 in the spacing ring 5 on the front gear plate 4 as shown.

The outer end of the finger 45 is provided with a lug adapted to be engaged by the thumb nail or by a suitable instrument and the finger pulled outwardly thereby rocking the bell crank lever in the proper direction to turn the shifting plate 31 and thus disengage the stem winding mechanism from the winding gear of the main set of works and into engagement with the winding gear of the supplemental set of works. Then the finger 45 is pushed inwardly and the bell crank lever 48 thus disengaged from the plate 31 the spring 42 will swing the plate 31 in the opposite direction and disconnect the stem winding mechanism from the winding gear on the supplemental set of works and engage said stem winding mechanism with the winding gear of the main set of works in which position these parts will remain until again shifted in the manner described.

By thus constructing and arranging the stem winding mechanism it will be seen that the same may be operated to wind either the main or supplemental sets of works said winding mechanism being also adapted to be wound by the key operated shafts of the springs ashereinbefore described. The hands 16 and 17 of the supplemental set of works may be set in any suitable manner and are here shown as having their arbors 167 projecting through the segmental sup-- porting plate 7 of the supplemental set of works and the adjacent portion of the plate 6 of the main set of works and with said projecting end of the arbor is adapted to be engaged a key whereby the hands may be set.

By constructing the watch as herein shown and described it will be seen that we have provided two entirely separate and distinct sets of works either of which may be removed and the other permitted to remain in the watch and by means of which when both sets of works are in position twovkinds of time may be kept so that the watch may be used for indicating the time of places in different longitudes.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention claimed.
